//! Runtime-owned public handles around compact internal indices.

//! Each handle carries an owner token from bind. Cross-runtime use returns
//! [`HandleError::ForeignRuntime`](super::error::HandleError::ForeignRuntime)
//! at the outbox and port-writer boundary instead of reading another instance's
//! dense storage.
